CodeCityApp turns coding practice into a daily quest loop: 1,551+ challenges across 13 language tracks, XP, streaks, ARIA AI mentor hints, 1v1 Arena battles, and a city that grows as your skills grow. It is built for learners who want momentum instead of tutorial hell: solve real challenges, learn to direct AI, catch mistakes, build your first agent, and see progress become visible.

CodecityApp's answer:
Codecademy teaches. LeetCode tests. CodecityApp builds habit. The city-building mechanic creates intrinsic motivation โ your skyline grows as your skills grow. Free forever with no meaningful limits, plus an AI mentor included. Competitors charge $20-40/month for less engagement.
CodecityApp's answer:
Self-taught developers and CS students who struggle to stay consistent with coding practice. Also bootcamp students who need structured challenge-based learning, and universities looking for supplementary practice tools for their CS programs.
CodecityApp's answer:
Built by Michael Clarke, a 50-year-old solo founder and ex-enterprise architect who got tired of boring coding practice. Every existing platform felt like homework. He built CodecityApp to make daily practice feel like progress โ city-building as the metaphor for skill-building. Week 9 of launch, pre-revenue, building in public.
CodecityApp's answer:
React, TypeScript, Vite, Tailwind CSS, Supabase (backend + auth), Anthropic API (Claude powers ARIA), Judge0 (code execution), Lovable (frontend development), EAS Build (mobile).
Weโve been using TestGorilla as part of our hiring process to screen applicants before bringing them into interviews, and itโs proven quite useful. The idea is simple but helpful: instead of spending hours reviewing resumes, you give candidates a relevant test right away. Seeing how people perform on real job-related tasks gives us a much clearer picture early on.
The test library is broad, covering everything from coding challenges and software proficiency to logical thinking and communication skills. Setting up and sending tests doesnโt take long, and the results are laid out in a clear way that makes comparison between applicants straightforward.
Where it falls a bit short is in the depth of some tests โ a few feel like theyโre too surface-level to really separate top performers from average ones. Creating your own custom assessments is possible, but the interface for doing that could use refinement. Also, once you scale up hiring, costs add up โ especially if every team needs access.
Overall, TestGorilla adds real value to the recruiting process by helping weed out unfit candidates early and giving objective data on skills โ which is why I give it 4 out of 5 stars.

What I had in mind was using either SHL-style aptitude tests, or third party assessments like testgorilla.com rather than a take-home exercise that I'd be moderating. I also remembered doing an online knowledge test of various web technologies when I used to be a web-dev - which could be useful for assessing Unity/C# knowledge. Source: almost 4 years ago
